CULTIVATOR.

Application filed May 15, 1924. Serial No. 713,631.

To all whom 2'25 may concern:

Be it known that 1, WILLIAM S. PRICE, a citizen of the United States, residing at Hershey, in the county of Lincoln and State of Nebraska, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to an attachment for cultivators and particularly to a device providing means for enlarging the working capacity of the cultivator.

The primary object of the invention is to provide attaching means for coupling auxiliary plow elements to the main plow elements of the cultivator so that the latter may be readily converted from a two row cultivator into either a three row or a tour row cultivator.

With the above and other objects in view the invention may be considered as residing generally in the particular details of construction, arrangement, and association of parts hereinafter described, reference being had to the accompanying drawing, wherein:

Figure 1 is a rear elevation of a two row cultivator with the attachment in place, and

Figure 2 is a detail view partly in section, illustrating the manner in which the attachment is coupled to the cultivator.

Figure 3 is a perspective view of a slight- 1y modified form of extension beam.

Describing the invention in detail, 10 designates a cultivator'of the two row type comprising a main beam 11 to which are connected a pair of laterally spaced sets 12 of revolving disks 13.

The attachment consists of an auxiliary set 14: of revolving disks 13 and a hollow extension beam 15, to one end of which the auxiliary set of disks is detachably clamped by means of the usual clevis 16 with which the disk set is ordinarily provided. At its other end the coupling beam is clamped to the main beam 11 by means of a clamp 17 as shown, so that the extension beam is extended substantially parallel with cultivator beam 11 and hence, positions the auxiliary set of disks 13' laterally of the main disks; the auxiliary set being adjustable lengthwise on the coupling beam so that the spacing between the various sets of disks clamp 17 is pivoted at its lower end on a bolt 18 extending through a hollow T head 19 at one end of the extension beam 15 and is so constructed as to present clamping jaws at its upper end which are adapted to embrace the main beam 11, suitable adj usting means being provided for tightening and loosening the jaws with respect to the main beam. Because of this arrangement, the extension beam can be adjusted longitudinally oi the main beam by merely sliding the clamp 17 inwardly or outwardly along the main beam after the clamping jaws have been sufficiently loosened, and the pivotal connection between the .clamp and the inner end of the extension beam provides for a certain amount of flexibility since the outer end of the extension beam is thus tree to have an up and down move ment as the disk13 rides over rocks, stones, or other obstacles in the ground. If desired, each end of the extension beam may be formed with a T-head and similarly equipped with a clamp 17, as shown in Figure 3; one clamp being designed for engagement with the main beam of the cultivator in the manner already described and the other clamp being adapted to hang downwardly for engagement with the crossbar of the auxiliary disk set 13, when the latter does not happen to be provided with a clevis 16.

By coupling the auxiliary set of disks to either the right or left side of the cultivator, the latter is readily converted from a two row cultivator into a three row cultivator and by attaching the auxiliary set of disks to each side of the cultivator, the latter may be converted into a four row cultivator, as will be obvious.

In addition to its use for the purpose outlined above, the attachment may also be used to couple the auxiliary set of disks, or any other type of earth-working elements, in trailing position with respect to the disk sets of the main beam. This may be done by simply turning the clamp 17 on the main beam until it points rearwardly, and at the sametime, swinging the extension beam on its pivot until it extends in alignment with the clamp and at right angles to the main beam with the other clamp 17 supporting the auxiliary set of disks.

From the foregoing it is thought that the objects and advantages of the invention will be readily apparent and that further detailed description thereof is not required.

What is claimed is:

1. An attachment for a cultivator com prising an extension beam having a hollow T-head at each end, a bolt extending longitudinally of each T-head a clamp associated with each T-head and presenting divergent members between which the T-head is re ceived, said divergent members being pivoted on opposite ends of the bolt, each clamp having clamping jaws at its outer end and an adjustable connection between the said clamping jaws.

2. An attachment for a cultivator comprising an extension beam having a hollow T-head formed integral therewith, a clamp presenting clamping jaws at one end and divergent members at its other end, said divergent members being adapted to receive the T-head therebetween means for pivotally connecting the said divergent members with the said T-head of the extension beann and an adjustable connection between the said clamping jaws.

In testimony whereof I afiix ture.
